Starting from iron smelting

Liu Meng digested this knowledge with difficulty, and finally raised a question: how to control combustion during iron smelting so that carbon can produce carbon monoxide to react with iron?

When Lu Xiuyuan heard Liu Meng's question, he smiled and nodded to show his understanding. He knew that this question involved a key link in the ironmaking process, so he patiently explained:

“Controlling combustion is actually a very delicate process that depends on the temperature in the furnace, the characteristics of the ore, and the supply of combustion medium.”

"In the blast furnace, we need to ensure that the burning coal can provide enough heat, but not too much, otherwise the temperature in the furnace will be too high and affect the stability of smelting. At the same time, we also need to control the supply of air to ensure that the carbon monoxide gas produced by the combustion of coal fully reacts with the iron oxide in the iron ore to produce reduced iron."

"To achieve this, the ironmaking process usually uses a pre-calculated mix with calculated amounts of reactants, and controls the atmosphere and temperature in the furnace by adjusting the input of coal and air. In addition, some combustion aids are added to the blast furnace to promote the combustion of coal and optimize the production of carbon monoxide."

"In general, the ironmaking process requires the use of a variety of technical means and equipment to effectively control the combustion process and achieve the reduction of iron ore."

Liu Meng listened attentively, pondering Lu Xiuyuan's explanation and trying his best to understand the mystery. Gradually, he gained a deeper understanding of the control process of ironmaking technology, and his doubts gradually dissipated.

"I see." Liu Meng nodded secretly in his heart, "Controlling combustion is like manipulating a flaming sword. It requires meticulous regulation."

"That's right." Lu Xiuyuan looked at Liu Meng approvingly, "Only by deeply understanding the principles and techniques of the ironmaking process can you flexibly apply them in practice and become a true ironmaking craftsman."

Then Lu Xiuyuan and Liu Meng said that if they went to Beiya Cave, they would be in danger of death. Even if they could not come back, they could rely on this skill to have food and clothing for the rest of their lives.

Liu Meng said, I can't help you, is there anything I can do for you?

Lu Xiuyuan thought for a while and said, you can make me a set of armor to protect my torso, which will greatly increase my chances of survival.

After that, Lu Xiuyuan took out a pen and paper, drew a blueprint of the armor according to the appearance of the armor in his mind, and gave it to Liu Meng.

Liu Meng took the blueprint handed over by Lu Xiuyuan and carefully examined the design. The lines of the armor on the blueprint were simple and clear, and every part of it exuded a strong and stable atmosphere. He couldn't help but sigh at Lu Xiuyuan's design ability. He was able to draw such a beautiful blueprint in such a short time, which was really impressive.

"Is this your design?" Liu Meng asked, with admiration in his eyes.

Lu Xiuyuan nodded and said proudly: "Yes, this is a set of armor I designed based on my own needs and experience. I think it can provide the greatest guarantee for my survival in Beiya Cave."

Liu Meng carefully observed every detail on the drawing. He could feel Lu Xiuyuan's dedication and concentration. In his opinion, this set of armor is not just a simple piece of equipment, but more like a belief, a desire and pursuit for survival, and a resistance and struggle against powerful oppression.

"This is a good design." Liu Meng nodded approvingly, "I will do my best to build a set of sturdy and durable armor according to your requirements."

Lu Xiuyuan smiled with relief. He knew that he had given Liu Meng a difficult task, but his trust in Liu Meng's ability had never wavered.

"Thank you, Brother Liu." Lu Xiuyuan said sincerely, "I believe you can complete this task."

Liu Meng patted Lu Xiuyuan's shoulder gently, indicating that he would do his best. "Don't worry, I will make this armor strong and durable to protect your safety."

The two of them sat down together and began to discuss the details of making the armor. Liu Meng asked Lu Xiuyuan about his requirements for the armor, and then began to prepare materials and tools. They chose the most durable iron block as the main material, and mixed it with a small piece of Phoenix red gold bought on the black market to create a set of sturdy armor.

In the next few days, Liu Meng devoted himself to the work of making armor. He carefully selected each piece of iron, patiently polished, baked, and hammered it, striving to make each piece of armor perfect.

Liu Meng and Lu Xiuyuan sat down together and began to discuss the details of the armor. Lu Xiuyuan described in detail his requirements for the armor: it needs to be strong enough to withstand various attacks, while maintaining flexibility so as not to affect his movements. He also emphasized the protection of key parts, hoping that the armor can cover as many important parts of the body as possible to ensure that he can be protected to the greatest extent in critical moments.

Liu Meng listened carefully and took Lu Xiuyuan's request to heart. He knew that this set of armor was extremely important to Lu Xiuyuan and he could not afford to be careless. So he began to prepare materials and tools and carefully crafted this set of armor.

Liu Meng was very careful in selecting materials. In addition to choosing the strongest and most durable iron, he also bought a small piece of Phoenix Red Gold from the black market. This is an extremely rare metal with extraordinary strength and toughness. Although Phoenix Red Gold is expensive, Liu Meng felt that it could add more strength and defense to the armor, so he did not hesitate to mix it into the armor.

In the next few days, Liu Meng devoted himself to the work of making armor. He carefully selected each piece of iron and used hammers and forging tools to beat it into various shapes and sizes. Under his skillful hands, each piece of iron became smooth and solid, revealing a strong metallic smell.

During the grinding and baking process, Liu Meng was extremely careful. He not only had to ensure that the surface of each piece of iron was smooth and flat, but also that its internal structure was tight and solid. He knew that only through meticulous processing could he create a set of armor that truly met Lu Xiuyuan's requirements.

Throughout the production process, Liu Meng and Lu Xiuyuan worked closely together, cooperating with each other to overcome difficulties one after another. They constantly adjusted and improved the design of the armor, striving to achieve the best defensive effect.

Lu Xiuyuan assisted Liu Meng and provided him with necessary help and support. He often made suggestions and helped Liu Meng solve problems encountered during the production process to ensure the quality and stability of the armor.

After several days of hard work, Liu Meng and Lu Xiuyuan finally completed a set of sturdy and durable armor. They checked every detail together to make sure there were no flaws in the armor. Every piece of iron was polished to a shine, and every weld looked solid and delicate, making it clear at a glance that this was a carefully crafted masterpiece.

This set of armor not only looks exquisite, but also has golden patterns on it, as if it is shining in the sun. Especially the small piece of Phoenix Red Gold embedded in it, which adds a mysterious and noble atmosphere to the whole armor. Phoenix Red Gold is an extremely rare metal with extraordinary strength and toughness. Its power has been widely praised. Therefore, once it is added, the defense of the armor will be greatly improved.

Looking at the armor, Liu Meng and Lu Xiuyuan couldn't help but feel proud of their achievements. They knew that this was not just an ordinary armor, but a precious testimony of friendship and trust. This armor witnessed their joint efforts and solidarity, their mutual support in the face of difficulties, and their determination and courage to meet challenges together.

Moreover, this set of armor is solid and can withstand all kinds of severe tests. Whether it is the claws of monsters or the sharp blades of enemies, it is difficult to cause substantial damage to it. It is like an indestructible iron wall, protecting Lu Xiuyuan's safety in the Beiya Cave.

"This armor is amazing!" Lu Xiuyuan exclaimed excitedly, "I can't believe we can create such a perfect piece."

Liu Meng smiled and said that he had only done his bit. "This is the result of our joint efforts." He said, "I believe that with this set of armor, your ability to survive in Beiya Cave will be greatly improved."

Lu Xiuyuan patted Liu Meng's shoulder gratefully, "Thank you, Brother Liu. With your help, I can face the challenges of Beiya Cave with more peace of mind."

"Thank you, Brother Liu." Lu Xiuyuan shook Liu Meng's hand gratefully. "With this set of armor, I have more confidence."

Liu Meng said, you can wear this armor inside at ordinary times to avoid being spotted by the enemy, and attack by surprise.

Moreover, this armor is not too heavy and fits your body well, so your movements will not be hindered after you put it on.

Lu Xiuyuan agreed with Liu Meng's suggestion, and he thought that this would make better use of the advantages of armor and bring more surprises and pressure to the enemy. After listening to Liu Meng's words, Lu Xiuyuan's eyes flashed with excitement. He knew that when facing a powerful enemy, an unexpected attack could often achieve greater results.

Therefore, Lu Xiuyuan decided to use the way of wearing armor as one of his tactics. He would hide the armor under his usual clothes so that the enemy would not notice that he was ready. This unexpected tactic would give him more advantages on the battlefield and make it difficult for the enemy to deal with.

The sun shone brightly on the golden armor, and every piece of iron reflected a dazzling light, as if it was coated with a layer of gold. Lu Xiuyuan stood there, his posture was upright and majestic, and the light from the armor projected on him made him look more majestic and powerful. From a distance, he was like a golden fortress, and it was impossible to ignore his existence.

This armor is not only stunning in appearance, but more importantly, it contains power. The addition of Phoenix Red Gold greatly improves the armor's defense and durability, making Lu Xiuyuan safer in battle. This is not just a set of armor, but also a symbol of strength, a belief in protection, which makes him full of confidence and courage on the road ahead.

When Lu Xiuyuan put on this dazzling suit of armor, the atmosphere around him seemed to become solemn and dignified. His companions showed envy and admiration, because they knew that with the protection of this suit of armor, Lu Xiuyuan would be more indestructible and more courageous.

In Lu Xiuyuan's heart, the armor represents an even greater meaning. It is his sharp blade for fighting, a solid barrier for him to protect himself and his companions, and a symbol of his everlasting faith and courage. Every time he puts on this set of armor, Lu Xiuyuan feels a strong force surge into his body, making him ready to face any challenge and test.

The dazzling appearance of the armor is only part of the story. What is more important is the power and courage it contains. Under this shining armor, Lu Xiuyuan will become an invincible warrior, marching forward bravely for his beliefs and glory, fearless of any difficulties.

After putting on the armor, Lu Xiuyuan felt as if he had been reborn, full of strength and vitality. He realized that it was not just the effect of the armor, but the confidence and faith it brought. Although the appearance of the armor was dazzling, what was more important was the inner strength it gave him, which made him more calm and confident in battle.

Lu Xiuyuan was surprised at the change in his aura. He didn't expect that the level of his equipment would have such a significant impact on his aura. This made him think about the relationship between equipment and cultivation. Perhaps in future cultivation, he could also enhance his strength by continuously improving his equipment level.

In order to verify the defensive effect of the armor, Lu Xiuyuan asked Liu Meng to conduct an attack test. Although Liu Meng declined, he finally acted according to Lu Xiuyuan's request. He drew out the nine-ring broadsword, jumped high, and swung it violently at Lu Xiuyuan.

Liu Meng swung the broadsword in his hand with great force and power, slashing towards Lu Xiuyuan with a chilling chill. The blade of the broadsword flashed coldly under the sunlight, like a bright moon appearing out of nowhere, cutting through the night sky, carrying with it an endless killing intent.

Lu Xiuyuan closed his eyes tightly, feeling the tremendous power brought by the blade, as if the whole valley was trembling. The surrounding trees were attracted by the blade light, and as the blade swung, the leaves fluttered, the branches swayed, and the shadows of the trees were mottled, as if adding a mysterious color to this duel.

Suddenly, a crisp metal collision sound rang out in the valley, like a note hitting the heartstrings, instantly stirring the entire valley. The surface of the armor made a crisp metal collision sound, but it firmly resisted the impact of the blade, protecting Lu Xiuyuan's body from any harm. Only a few minor scratches were left on the armor, shining as new, but there were several obvious gaps in Liu Meng's sword, which was blocked by Lu Xiuyuan's solid armor. The collision of strength and determination stirred in the valley.

This scene also surprised Liu Meng. He did not expect that Lu Xiuyuan's armor was so strong that it could withstand such a fierce attack. He could not help but secretly praise: "What a strong set of armor!" Although his attack was blocked, he felt an invisible respect in his heart, and he was in awe of Lu Xiuyuan's fighting ability and wisdom.
